RECORDING DEVICE FOR SIGNAL SYSTEMS.

Specification of Letters Patent. Patented Dec. 13, 1921.

.lpplication 'flled June so, 1916. Serial No. 100,779.

To all it may comm:

Be it known that '1, PETER PAYNE DEAN, a

subject of the King of En land, and resident of the borough of anhattan, city,

county, and .State of New York, have 111-.

vented certain new and useful Improvements in Recording Devices for Signal Systems,-of which the followingiis a specification.

' The device, the subject of this invention, is especially intended as a means for'assist ing 1n the operation of steamships, steam boats or mechanically propelled water craft;

and has for its principal objects the rovision of recording apparatus which w not only record the signal transmitted by the ships telegraph, but will also record the action of the engine which results because of the signal that has been transmitted.

It has often occurred that where a multiplicity of signals have been transmitted in rapid succession from the bridge tothe engine room the engineer or-operator has not responded in the order in which the signals were transmitted with the results that accidents have occurred which'have resulted in loss of life and destruction' of roperty. When an accident occurs difficulty is experienced in placing the responsibility because of the fact that confusion of signals.

might result from a rapid transmission and also it'has been found that when a definite space of time does not elapse between sig nals, the mind of the operator is notin .fluenced; to a sufficient extent to cause the desired'responsaa After an accident under ordinary conditions', it becomes a question asto just what signals were given and what signals were responded to. In my; device such a question could not arise aseach signal is recorded upon a suitable chart that has taken place as the result of the signal.

vice will be fully. set forth as the spec1fication progresses.

The following is what I consider the bes means of carrying out this invention in which; 1 Y Fi 'e 1 shows a ships telegraph to whic lth e operating portion of my device is attached.

Similar reference'numerals indicate like parts in all the figures where they appear.

In Fig. 1, I show in front elevation the sending device of a ships telegraph. This device 1s of an ordinary construction except for the additions that I havemade which will be described as the specification progresses.

The sending devices or signaling pedestal as they are 'enerally termed are arranged one in the pilot house and usually one or more on the bridge and it is often convenientto arrange other similar devices at different parts -ofthe ship to be used in docking or m running under extraordinary conditions. w

This sending device consists of the dial 1 which is supported upon a edestal 2. The

dial-has a face of-glass subivided as shown across'which an operating handle 1' may be passed. Under ordinary conditions the "handle is moveddneither direction, to therig-ht when the boatis to be operated ahead and to the left when the reverse operation or a. movement astern is desired. The operation of the handle to any position introduces into a convenient circuit a lamp which will illuminate that portion of the dial at which the handle is brought to rest and as a similar dial is rovided in the engine room, and as the amps of both dials are The construction and operation of my dein series, when the lamp illuminates the sendin or brid e dial, the engine room be sim' arly illuminated and here I desire to call attention to the fact that in the ordinary construction the movement of the handle fromv the" center to the full movement in either direction will cause a dial over which the handle has passed. This momentary illumination is exceedingly confusing. I call attention to the ordinary constructionso that my improvements may be more readily appreciated and understood.

Uponthe shaft which supports and which is operated by the handle 1 I securea pulley or sprocket 3 and over this pulley or sprocket I gass a belt or chain 4.

- n approximate alin'ement 'with the sprocket 3 I arrange another pulley or sprocket 5 which is supported upon a suitable shaft 8 arranged in the casing 6 and the casing is'secured by means of bolts or rivets 7 to the exterior of the pedestal .2.

, And now, referring to Figs. 4 and 5 I will describe in detail the construction of the mechanism which is arranged within the casing 6. Y 7

This device is a contact maker. Thesprocket5 is secured to androtates the shaft 8 and upon this shaft I also secure a sector I supply may be secured and the opposite end of the plug 11 contacts with a commutator which consists of a plurality of independent strips of copper or other suitable metal as shown at 14. As the plug 11 is caused to pass along the strip 13 and across the commutator a circuit will be completed,

. but it is to be desired that no indication of the movement of the sector shall be made or recorded except such movements as are,

- to be considered as signalingmovements.

I have therefore provided'a means whereby the circuit will be interrupted during the movement of the sector and will be only reestablished when the sector is brought torest in the desirable position, this means comprising a pinion 15 which is rotated from the sector 9 andthe" relation between the sector and pinion is such as tocause a rapid v revolutlon of the pinion during the movement of the sector.

The pinion l5 issecured to a shaft 16 which shaft ismounted between'a bearing block 17 andone side of the casing 6, and uponthe shaft 161 'secure'a collar 18 which supports one end of flexible members 19.. The 'other'fend of these-flexible members is;

secured to a movable collar 20 attached to whlch 1S3, disk 21 and a plurality of weights 22 and 23 arranged upon-the flexible member complete the governor which shortens the distance between thecollars 18 and 2 0 when the shaft'16 is rotated. Supported by the casing 6 but insulated therefrom. is a plurality of contact points 24 and These: points which are in line with the disk 21 may e connected into a source of current supply and the disk 21 bridges the gap between lithe points 24 and 25 completing the circuit therethrough. g

In Fig.2 I-show a, casing 26, in which is mounted an indicating device consisting of 'a magnet 27 and, an armature 28. Secured to the armature 28, which will terminate in a pen point,is a pointer.

In the other half of the casing 26, I show a plurality of pointers 30 each pivoted as indicated at 31, and each of the pointers 30 should terminate in a pen point. Under the series of pen points or pointers 29 and 3O. and in the spaces indicated at 32 and 33 I 'pass' a chart or long strip of paper subdividedvin a manner to be later described and each operation. of any of the pointers will be indicated upon the paper strip or chart. The pointers indicated at 30 are each connected with one of the commutator bars 14 and cause a record to be made upon the chart of each effective. movement of thesector 9. The pointer 29 operated by the armature 28 and magnet 27 is controlled and is caused to move by a magneto 34 driven by a, friction wheel 35 from the engine or propeller shaft 36. z

Now I will describe the method of operation of my devicelandin' doing so Iwill refer to the'diagramshown in Fig. 6 and the chart shown at Fig. 7, and upon this diagram and chart I will place reference characters corresponding to the characters used upon the figures which 'showthe mechanical construction of the parts referred to.

. The magneto whichis driven from the engine or propeller shaft is indicated at 34} in'Fig. 6 and the leads or wires which are.

connected. therewith terminate, at the armature 28 of. the larger recording device shown inthecasing 26. When theshaft 36 is at rest no current-will be generated. by the mag neto34 and thereforethefpensorl pointer 29 "will remain stationary upon the center line i 38. When however the engines are causing the shaft 36 to rotate the pen 29 will be de-- flected in the direction offthe arrow F if the engine is running ahead, or inthe direction of the arrow, B, when the engines are reversed. This movement of the pen will cause it to inscribe a. deflected line on the 1 "chart shown in Fig. 7, the deflection being. in the, direction of'and' toward the point 39 during the reverse movement of the engine and inthe direction of and toward-the pointt 40' during .a forward? movement of theengine, and it will be observed that the chart is subdivided by a number of longitudinal lines and that these lines are indicated at* zero 100, and 200 and these figures indicate the speed at which the shaft 36 is revolving.

- It will be noted that the other half of the sions of the dial 1.

In Fig. 6 a battery or source of electrical will return-"to the normal spaces in which the lines are produced are indicated in a' manner to exactly correspond with the indications in the several sub-divisupply is shown at 41, a lead from the battery is carried. to the contact 24 and from I the contact 25 a suitable wire is carried to the coils 42, these coils which are arranged within the casing 26 are the magnet coils for the several pointers 30 and all may have one side connected to the lead from the contact 25. The opposite side of each armature coil 42 is connected to a commutator bar 14 and the other side of the battery is connected through a suitable lead wire 43 to the plug 11. I

When the handle 1" is in the position shown in Fig. 1, the plug 11 is in contact with the centermost commutator member 14 and if at this time the disk 21 has closed the circuit through the contacts 24 and 25 this Section .of the dial 1 will be illuminated. At any.

rate the-several pens 30 will draw straight lines on the upper portion of the chart. Now when a movement of the handle to the right takes place the disk 21 will be withdrawn until the handle 1' is brought to rest at which time the portion of the dial over which the handle is allowed to rest will be illuminated and at the same time the pen which is connected or energized by the passage of current through its magnet will be deflected with the result that the line which it is producing will be distorted as indicated at 44. This distortion will continue un'til the movement of the handle 1' deenergizes the armature of this pointer, when the pointer position to produce astrai ht line.

In t e chart I have shown a distortion of each of the pens in turn and I have also shown the result of the several move ments as each ofthe lines drawn by the pens is broken or distorted. It will be understood that the movement of each pen 30 is occasioned by the movement of the handle 1' which causes an operation of the sector 9 and the plug 11 carried thereby, and that the pen 29 is entirely under the influence of the magneto 34 which is driven from the shaft 36.

. I desire to call articular attention to'the chart shownin Fig. 7 and to the transverse line thereon which lines indicate spaces of time as shown by the figures arranged along the upper end of the chart. A suitable clock work or timing mechanism should be pro V ided for moving the chart and the deflec- 410118 of the lines R to F will indicate the length of time that the handle 1 was retained in any position.

invention what I claim and The deflections in the speed lines, the line on the other ortion of'the chart will indicatenot only t c direction and speed of rotation of the engine or propeller shaft but also any changes in direction and for how long a time each direction was maintained, and at the exact time that the change occurred. This is exceedingly important as it proves'conclusively whether or not a signal was responded to and at just what time the response took place, and will also indicate the time which elapses between the sending of the signal and the response thereto, the Whole being contained open a record, chart or-sheet that may be retained for future reference or information. a

It is quite obvious that modification may be made in the construction and that changes in the mechanical arrangement or locat on 7 of the parts to adapt the device to operate without departing from the principle or.

sacrificing the advantages of this invention. The Figs. 1,2, 3, 4 and so forth, along the upper edge of the chart shown in Fig. 7, indicate the time as sub-divided into minutes. I may shorten the space so that the sub-division will indicate five minutes or a greater of time, .or I may lengthen the space so that signals maybe read when such changes are made. It will of course be necessary to increase or decrease the speed of the clock work not shown by means of which the chart-is moved.

I may connect the illuminating means for the dials with the device shown in Fig. 5, so that the current will pm through the lamps only when the handle 1' is at rest, or may use such a device in communication w th illuminated dials with the obvious advantage that only that portion of the'dials which indicate the signals to be transmitted will be illuminatedeven during the movement of the handle. 3
